Answer:
Step-by-step explanation:
the diagonal is the hypotenuse of a 45-45-right triangle
the two legs are the same measure so the Pythagoreant theorem
2x²=24 divide by 2
x² = 12 square root
Answer:
4 : 7
Step-by-step explanation:
Given 2 similar figures the if the ratio of perimeters = a : b
The the ratio of areas = a² : b²
Here
ratio of areas = 16 : 49 , then
ratio of perimeters = 
: 
= 4 : 7
Answer:
27cm
Step-by-step explanation:
first, separate the 2 shapes you will find the area too. these would be the little 3 by 3 block sticking out on top, and the other piece.
to find the area, you have to do length times width.
you can start off with the 3 by 3 block. 3 times 3 = 9cm
next, you have to find the measurements of the rectangular shape. we know the width is 6cm. and the length of the whole shape is also 6cm. but we can take off the 3cm from the other shape. we now have 3cm leftover to be the length for the rectangle.
we can now find the area for the rectangle. 6 times 3 = 18cm.
last but not least, we can add the 2 measurements up to get the area of the whole shape. 9 + 18 = 27cm.
Answer:
189/16 inches squared
Step-by-step explanation:
When you are multiplying mixed numbers it is best to change them to improper fractions if it is easier for you.
2 1/4=9/4
5 1/4=21/4
If you simplify it, it will be 11.8125
Hope this helps! May I have brainliest I need to rank up.
The answer should be 15 times 9 equals four
